LAOS: The strain softening/strain hardening paradox
Journal of Rheology, 2014Numerous materials, from biopolymers to filled rubbers, exhibit strain softening at high strain amplitudes during a strain sweep in oscillatory rheology: The modulus decreases with increasing deformation. On the other hand, if the nonlinear elastic response is analyzed within a single oscillation cycle (described by a Lissajous curve), these systems ...

On Strain-softening in Dynamics
International Journal of Fracture, 2004On the basis of a discussion on the existence of strain-softening in concrete, a monotonic constitutive law, the effective law, has been proposed by the present author. The identification of the effective parameters has been performed for quasistatic load processes.

The nature of directional strain softening
Scripta Metallurgica, 1983Softening transients are sometimes seen in metals following a change in direction of straining. One example of such softening is that occuring upon a strain direction reversal, for example, during uniaxial reversed cyclic deformation at a large strain amplitude.

Continuum Theory for Strain‐Softening
Journal of Engineering Mechanics, 1984In heterogeneous materials such as concretes or rocks, failure occurs by progressive distributed damage during which the material exhibits strain‐softening, i.e., a gradual decline of stress at increasing strain. It is shown that strain‐softening which is stable within finite‐size regions and leads to a nonzero energy dissipation by failure can be ...

A discussion of strain-softening in concrete
International Journal of Fracture, 2004The question of whether concrete strain-softening is a real material property is discussed here. The discussion is given from both the physical and the analytical point of view. New evaluations of the actual nature of strain-softening are added to those existing in literature.

Deformation of strain softening materials
Computers and Geotechnics, 1985Abstract This paper is a continuation of the research initiated by the first author and Z. Mroz [1] during the 1980–1981 period. It is intended as a prelude to a series of articles which extend the concepts and ideas introduced at that time. In the present article, finite element analysis for conventional strain-softening concepts is provided ...

Strain softening in an epoxy resin
Journal of Materials Science, 1982Post-yield behaviour, particularly strain softening, has been studied here for an epoxy resin to examine the effects of postcuring and plasticization by water and a non-volatile diluent dibutylphtalate. The significance of necking was examined by conducting compression tests (at room temperature) as well as tensile tests.

Strain Softening in Rat Left Ventricular Myocardium
Journal of Biomechanical Engineering, 1994We investigated whether strain softening (or the Mullins effect) may explain the reduced left ventricular stiffness previously associated with the strain-history-dependent preconditioning phenomenon. Passive pressure–volume relations were measured in the isolated, arrested rat heart during LV balloon inflation and deflation cycles.
